DYNAMITE.

SPECIFICATION forming part of Let ers Patent No. 372,338, dated November 1, 1887.

Application tiled July 5, 188%. Serial No. 243,380. (No specimens.)

To all whom it may concern.-

Be it known that I, SERGEY DARK SMO- LIANINOFF, a citizen of the United States, residing in the city and county of San Francisco. btatc of unmet-ma, have ini/ented a new and useful Iligh Explosive, of which the following is a specification.

My invention relates to improvements in high explosives; and itconsists in the employment of nitro -glycerine absorbents which, when burned, will produce a high degree of expansion.

I employ asbestns, nitrate of potash, and chloride of potash, as follows: I take fibrous asbestus, carefully assorted, and saturate with fnllsolution of equal parts of nitrate of potash and chloride of potash. I dry the same earefnlly-stirring to dry evenly-then press into thin cakes and bake until fully dry and brittle. I thonpulverize, bygrinding to afine powder, and mix it with pure nitro glycerine, in proportion of seventy-four per cent. nitroglycerine to twenty-six per cent. of the mixture ofasbestus, nitrate of potash, and chloride 25 of potash prepared as above described.

This compound may be packed closely, absorbs heat slowly, and is not easily affected by the action of the atmosphere. Its expansion by l lfiltisml beat n burning it: inc-messed hr its etTectiveness abovethat of No. 1 dynamite. a Asbestus is preferable to infusorial earth or wood pulp, for the reason that where the asbestus is employed thereare no injurious gases, as a greater amount of oxygen remains than where it is required in the combustion of our 35 bon or other substances which may be contained in the absorbent.

I do not confine myself to asbestns, as other absorbents may be substituted by retaining the other features of the compound.

Having thus described my invention, what I claim, and desire to secure by Letters .latout, is r The combination of asln-stus, nitrate of potash and chloride of potash, and nitro-glycer- 45 inc, as and for the purposes set forth.
